   Hi all!

   My idea is to improve the plugin to have several attributes in the shortcode, that I could pass to the FlexSlider js param array.

   I'm trying to pass [gallery slideshow="auto"].

   Here's the code:

   //member of class MV_Gallery_To_Slideshow
   function set_slideshow( $params, $attr ){
   		switch($attr["slideshow"]) {
   		    case "auto":
   			$params['slideshow'] = true;
   		    break;
   		    default:
   			$params['slideshow'] = false;
   		}
   		return $params;
   	}
   ....
   
    function enqueue_script() {
   ...
   
   add_filter( 'mv_gallery_to_slideshow_attr', 'set_slideshow', 10, 2 );
   
               wp_localize_script( 'gallery-to-slideshow', 'mv_gallery_to_slideshow_js_params', apply_filters( 'mv_gallery_to_slideshow_js_params', $params ) );
   }

   What am I doing wrong, please?

   Had to take my head to the code and finally found a solution:

   I moved
   

   // FlexSlider Params
               $params = array( ... );
   wp_localize_script( 'gallery-to-slideshow', 'mv_gallery_to_slideshow_js_params', apply_filters( 'mv_gallery_to_slideshow_js_params', $params ) );

   from function enqueue_script() { ... }

   to

   function gallery( $gallery_html, $attr ) {
   ...
   
   // FlexSlider Params
               $params = array( ... );
   
   if( isset( $attr['slideshow'] ) ){
   		$params['slideshow'] = $attr['slideshow'];
   	    }
   
   	    wp_localize_script( 'gallery-to-slideshow', 'mv_gallery_to_slideshow_js_params', apply_filters( 'mv_gallery_to_slideshow_js_params', $params ) );
   ...
   }

   Hey Alvelig,

   This sounds perfect for what I'm trying to achieve - but I'm struggling to follow what you're doing. Did you do this by adding a filter in your function.php file which adds the shortcode attributes, and passes them into a localized script, or did you modify the core plugin file?

   If there's any chance you could post a more complete example that would be very much appreciated!

   Thanks

   Andrew

   Hi Andrew!

   Actually, i was editing the plugin files (inc/gallery-to-slideshow-class.php)... And the second post is more a feature request for the developers, than an out-of-the-box solution.

   But as far as functions.php is concerned, I can assume that adding these lines to functions.php should do the job. Actually, i tested it, heh )
   

   add_filter( 'post_gallery', 'my_hook_for_gallery', 11, 2 );
   
   function my_hook_for_gallery ( $gallery_html, $attr ) {
   	if( isset( $attr['slideshow'] ) ){
   		$params['slideshow'] = $attr['slideshow'];
   
   	    wp_localize_script( 'gallery-to-slideshow', 'mv_gallery_to_slideshow_js_params', apply_filters( 'mv_gallery_to_slideshow_js_params', $params ) );
   }
   }

   Update: the $attr['slideshow'] can be any attribute of the gallery shortcode.

   Hey Alvelig,

   Thanks so much - really much appreciated.

   After some fiddling last night I managed to get it working - but for some reason it only works if I add

   return $gallery_html;

   within the function - otherwise it outputs the standard gallery html. Does that sound right to you?

   Andrew,

   that sounds right and so is it, but now I wonder, why the code above worked in my case without return $gallery_html; :)

   Another thing: did you manage to do anything with MCE Rich Text Editor. I am looking for a solution to add gallery and its attributes not in HTML mode, but in Visual.

   Hi Alvelig,

   I can't find a way of doing that immediately - but this plugin seems to be doing something along those lines:

   http://wordpress.org/extend/plugins/file-gallery/

   I'm also looking for way to link each slide to a url - one that isn't the full-size image or the attachment url (ideally the link-url on the image). You don't know if that's possible do you?

   Andrew

   Andrew,

   thank you, your link is really helpful, that plugin seems to be awesome. :) But a bit sophisticated, so for the current project I won't switch to it.

   As for external link on slides, it's possible using add_post_meta()/ get_post_meta(). I think you can use an a little outdated though useful plugin: http://wordpress.org/extend/plugins/media-custom-fields/ which adds custom fields to post attachments (media posts).
   and then you'll have to get your custom meta field with get_post_data()

   Sorry for not giving you a complete solution, but this should help resolve your problem.
